How can I temporarily disable an animation?
In all 3 windows


Graph editor Window
Dope Sheet Window
NLA Edit Window


... it is possible to toggle the mute button of the channel transformation.  Contribution can be active or inactive.

Thus if the timeline were on frame 88 and the sphere was animated to rotate and the Blender User decided to disable the contribution of the channe .... then the sphere would no longer rotate dynamically and it would be frozen at the rotation of frame 88.  Later the contribution can be turned on again.  Blender uses the word mute so I am partially conforming to that jargon.



Image above. [Contribution/No Contribution] or Mute button has the shape of a speaker.  Speaker has no sound marks. Contribution inactive.
